M5.2 Earthquake near western Indian-Antarctic Ridge — March 18, 2022
2022-03-18 02:52:45 UTC (2022-03-18) · approx. 10:52 AM UTC+8 local
On March 18, 2022 at 02:52 UTC, a magnitude 5.2 shallow crustal earthquake struck near western Indian-Antarctic Ridge, at a depth of 10.0 km and coordinates -49.3443°, 121.2306°.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
